    摘要: The present invention provides a surface emitting laser and a photodiode which permit secure mounting even in mounting by flip chip bonding, and high-speed modulation. The present invention also provides a manufacturing method therefor and an optoelectric integrated circuit using the surface emitting laser and the photodiode. Semiconductor stacked layers stacked on a semiconductor substrate have a light emitting portion and a reinforcing portion formed with a recessed portion provided therebetween, and a p-type ohmic electrode and an n-type ohmic electrode are formed on the top of the reinforcing portion. The p-type ohmic electrode is electrically connected to a p-type contact layer through a contact hole vertically formed in polyimide buried in the recessed portion to permit supply of a current to the light emitting portion in the thickness direction. The recessed portion has a groove formed to reach the semiconductor substrate, thereby suppressing the parasitic capacity between the p-type ohmic electrode and the n-type ohmic electrode.

    摘要: The invention provides an optical module, in which a surface-emitting laser and an optical fiber are coupled, with the optical axes thereof crossed at a predetermined angle, at low cost. A supporting member supports the end of an optical fiber, in which the extending direction of a through hole and a face at the optical fiber end are orthogonal to each other. A surface-emitting laser and the supporting member are coupled by metal projections having different heights, so that a light-emitting face of the surface-emitting laser and the face of the supporting member are disposed so as to be opposed to each other at a predetermined angle. After the projections are formed on an electrode and metal patterns on the surface of the surface-emitting laser by a method based on wire bonding, the leading ends thereof are fixed to metal patterns of the supporting member by ultrasonic welding.

    摘要: An optical pick-up according to the present invention is designed such that laser beams having different polarization directions or different radiation angles are irradiated from laser beam sources formed in a surface emitting laser array to change the effective numerical aperture of an optical element having an objective lens, or the like. An optical pick-up having high capability with an optical disk having a low recording density and a thick substrate according to the CD standard, and an optical disk having a high recording density and a thin substrate according to the DVD standard, can be realized. A plurality of laser beam sources can be formed in a small space by employing a surface emitting laser array, and the numerical aperture of the optical system can be controlled by selecting a laser beam. For this reason, an optical pick-up having compatibility can be realized with an extremely simple arrangement, and a compact and high-performance optical pick-up can be provided at low cost.
